GAS-LIGHT BURNER. i i

Application filed February 14, 1922. Serial 1T0. 536,462.

To all whom it may concern Be it known that I, FRANCIS DnGnUcHY, acitizen of the United; States, and a resident of Newark, in the countyof Essex and State of New Jersey, have invented new and usefulImprovements in Gas-Light Burners,

of which the following is a specification.

This invention relates in. general to gase ous fuel burners for lightingpurposes, and

more particularly to a gas-light burner of the flame type including a'tip for spread ing the flame for illuminating purposes. v The Ob]GCtS ofthe invention areto provide an illuminatingburner of the characterdescribed embodying novel features of construction whereby lightof highquality is obtained; to provide a construction for an illuminatingburner of this character which produces substantially completecombustion of the gaseous fuel and thereby a white, brilliantflame *3tothus )rovidea burner includ- I I ing a pair of spaced gas outletsandimproved means for d recting a current of air between said outlets intothe flame; to pr0-.

vide a burner including a body portion adapted to be connected to a gaspipe and having a pair of spaced gas outlets directed upwardly andinwardly toward each other whereby the flames from said outlets mergeinto each other, said body portion having opposite grooves thereinbeneath and between said outlets whereby the heat from said flames.draws air upwardly through said grooves into said flames; and to obtainother results and advantages as may be liigure 2 is a partial.transverse vertical.

sectional view and side elevation of the burner, and

lligure 2) is a top plan view thereof. In the embodiment of theinvention shown on the drawings the reference character A designates thebody portion of the burner which includes a. tubular portion 1interiorly threaded at one end thereof, (as at 2. for attachment to agas-pipe or the like, the

other end of said tubular portion communieating through an opening 3with a chamberA, which is formed at the end thereof with an upstandingburner tip supporting projection 5; The projection 5 is provided with aparrot spaced passages 6 communicatingwith the chamber. 4 and convergingupwardly toward each other, a burner tip 7 being mounted at theouter endof each of said passages 6, and the outlet slits 8; of said tips 7 beingarranged substantially parallel with each other and transversely of theprojection'ii. The projection 5 is also provided in oppositesidesthereof between the burner" tips? with substantially parallel grooves 9whichopen through the-top of the projecti'on and are separated by awall. 10 terminating short of the upper end. of the proection 5, asclearly shown in Figure 2 said grooves being disposed longitudinally-ofthe projection 5 and substantially in the plane bisecting theangleformed by the converg 'ance of the burner outlets.

With this construction when the burner is attached to a gas-pipe or thelike, the gas turned on and ignited at the tips 7,-the

flames B frointlie tips will merge into each other, as .clearly shown-1nFigure ,1, dueto the converging of the passages 6 and tips 7.

The heat from the flames B will cause a circulation of a current of airupwardly through each of the grooves 9 into the space between the flamesB, as indicated the arrows in Figure 2, and this air enteriiig theflaincswill cause a substantially complete combustion of the gas leavingthe tips 7. The currents of air rising through the two grooves 9 will,when they reach the top of the wall 10, impact with each other so as tospread substantially in the plane bisecting said angle of convergence ofthe burner tips and upwardly into the flames. This complete combustionof the gas makes the flames B substantially white in color,

brilliant and of a quality and 'quantity favorably comparable with thelight produced by. the well-known incandescent :DJZLIItlOS. I have foundthat by varying the depth of the grooves 9 the width of the flames B canbe varied, and that different shaped tops on the wall 10 will producedifferent shapes of flames. Thus, an in crease in the depth of thegrooves 9 will. produce a wider flame, and a square top on the wall 10will produce substantially a square flame. I

A plurality of superposed layers of fine mesh wire fabric 11 arepreferably arranged in the tubular portion 1 of the burner between thegas-pipe andthe chambers so.

as to filter the gas and provide a uniform.

possible embodiment of my invention, it will be understood that this isonly for the purpose of illustrating the principles thereof, and thatmany modifications and changes can be made in the detailvconstructionhofthe gas burner without departing from the spirit or scope of theinvention. Therefore, I do not desire to be understood as limitingmyself except as required by the following claims when: construed in thelight of the prior art.

Having thus described the invention, what- I claim is:

1. A gas-light burner including a body by the heat from said flame drawsa current of air upwardly through each of said grooves into the spacebetween said burner outlets where said currents impact with each otherand spread into said flames.

2. A gas-light burner including a body portion having a pair of spacedconverg 1;: burner outlets the flames from which merge together. saidbody portion being provided at opposite sides thereof between saidburner outlets with substantially parallel grooves disposedsubstantially in the plane bisecting the angle formed by the convergenceof said outlets and opening through the top otsaid body portion, saidgrooves being separated by a wall terminating short of the top of thesaid body port-ion, whereby the heat from said-flames draws a current ofair upwardly through each of said grooves over the top of said wallwhere said currents of air, impact with each other and are caused tospread substantially in said plane bisectingthe angle 01" con-verganceof the burner outlets and upwardly into said flames.
